Thor The Dark World Trailer Debuts: What Will You Sacrifice?

Thor: The Dark World trailer should in theory be weeks off. But, after a Marvel-laden day that included Movie Fanatic talking to the cast of Iron Man 3 and the first Thor The Dark World stills premiering, it appears the superhero factory is not done with us as the Thor sequel's first teaser has dropped like a hammer.

The clip begins with an establishing shot of the city of London. For us Anglophiles out there, we're off to a good start. Then... the Anthony Hopkins narration starts. "Some believe that before the universe... there was nothing. They're wrong. There was darkness and it has survived."

And stick around for the presence of someone you might have suspected would not appear in a Thor sequel after what happened in The Avengers -- Loki! "You must be truly desperate to turn to me for help," he says. Yes, indeed!
